For real values of argument , the values of the Airy functions and , and their derivatives and are real.

The Airy functions and , and their derivatives and have rather simple values for argument :

The Airy functions and , and their derivatives and defined for all complex values of , are analytic functions of over the whole complex ‐plane, and do not have branch cuts or branch points. These functions are entire functions with an essential singular point at .

The Airy functions and , and their derivatives and are not periodic functions.

The Airy functions and , and their derivatives and have mirror symmetry:

The Airy functions and , and their derivatives and have rather simple series representations at the origin:

These series converge at the whole ‐plane and their symbolic forms are the following:

Two sums in the previous formulas can be combined into one formula, and the resulting formulas can be rewritten as follows:

Interestingly, closed-form expressions for the truncated version of the Taylor series at the origin can be expressed in terms of the generalized hypergeometric function , for example:

The asymptotic behavior of the Airy functions and can be described through formulas that depend on the sector of (Stokes phenomenon). The following formulas are examples of asymptotic expansions that are valid for (for and ) and for the sector (for and ):

By using discontinuous functions such as , it is possible to write single expansions that are valid for all directions:

The Airy functions and , and their derivatives and have rather simple integral representations through sine, cosine, and power functions:

The argument of the Airy functions and , and their derivatives and can be simplified for third roots:

The derivatives of the Airy functions and , and their derivatives and have simple representations that can also be expressed through Airy functions:

The symbolic -order derivatives have more complicated representations in terms of the regularized hypergeometric function :

The Airy functions and appeared as special solutions of the simple-looking linear second-order differential equation:

where and are arbitrary constants.
Additional restrictions on and lead to corresponding Airy functions:
